Get-User (ExchangePowerShell)

The Get-User cmdlet returns no mail-related properties for mailboxes or mail users. To view the mail-related properties for a user, you need to use the corresponding cmdlet based on the object type (for example, Get-Mailbox or Get-MailUser). You need to be assigned permissions before you can run this cmdlet. Although this article lists all parameters for the cmdlet, you might not have access to some parameters if they aren't included in the permissions assigned to you. To find the permissions required to run any cmdlet or parameter in your organization, see Find the permissions required to run any Exchange cmdlet.
